Phylodynamics and phylogeography of watermelon mosaic virus: Multiple local invasion routes in southern France and recombination-driven limits to global analysis.

Watermelon mosaic virus (WMV) is a major plant pathogen, infecting over 170 plant species, including cucurbits and legumes. Though mostly propagated locally by aphids in a non-persistent manner, long-range dispersal can occur through human-induced plant or vector movements. Understanding patterns of local and global spread of WMV is crucial to help formulate adequate control strategies.

The multifurcating skyline plot.

A variety of methods based on coalescent theory have been developed to infer demographic history from gene sequences sampled from natural populations. The 'skyline plot' and related approaches are commonly employed as flexible prior distributions for phylogenetic trees in the Bayesian analysis of pathogen gene sequences. In this work we extend the classic and generalized skyline plot methods to phylogenies that contain one or more multifurcations (i.
